QUESTION:
Refrigerant-134a enters the compressor of a refrigeration system as saturated vapor at , and leaves as superheated vapor at and at a rate of .Determine (a) the mass flow rate of the steam and the exit velocity, (b) the total and flow energies of the steam per unit mass, and (c) the rate at which energy is leaving the cooker by steam.
ANSWER:
Step 1 of 3
Refrigerant-134a enters a compressor as a saturated vapor at a specified pressure, and leaves as superheated vapor at a specified rate. The rates of energy transfer by mass into and out of the compressor are to be determined.
Assumptions are
1. The flow of the refrigerant through the compressor is steady.
2. The kinetic and potential energies are negligible, and thus they are not considered.
The enthalpy of refrigerant-134a at the inlet and the exit are (Tables A-12 and A-13)
